Abstract
A method and an apparatus for treating titanium-containing slag is disclosed. The method comprises contacting a titanium-containing slag (2) with a first sulphuric acid leach solution (4) for dissolving impurities contained in the slag to obtain a first slurry. In the method, the first slurry (8) is subjected to a solid-liquid separation (10) to obtain a first sulphuric acid leach solution containing the dissolved impurities from a first titanium-containing leach residue (12).
